Martin Shkreli, charged with securities fraud and brought before the "imbeciles" of Congress for jacking up the price of life-saving drugs, now has another, if much smaller, problem on his hands.

The former drug company executive's one-of-a-kind, $2 million Wu-Tang Clan album includes nine portraits of the rap group's founding members used without permission, according to a complaint filed Tuesday in Manhattan federal court.

The artist, Jason Koza, has sued Shkreli, record producers Robert "RZA" Diggs and Tarik "Cilvaringz" Azzougarh, and Paddle8, the online auction startup hired to sell the album.

Koza, an artist and musician in Copiague, New York, claims he created portraits of each of the group's founders for the fan website WuDisciples.blogspot.com in late 2013 and early 2014 but never agreed to their use in the 174-page book that accompanied the album, "Once Upon a Time in Shaolin."

He says that on January 29 he saw an article published by Vice.com including photos of three of his Wu-Tang Clan portraits: "Raekwon-Koza," "Inspecta Deck-Koza" and "Ol' Dirty B--tard-Koza." He claims he applied for registration with the U.S. Copyright Office on February 1, and that Shkreli infringed his rights by allowing the three portraits to be publicly displayed.

Paddle8 announced in November that Wu-Tang Clan had sold the 31-track album, which came with a hand-carved box and a leather-bound book with lyrics, pictures and background on the songs. Bloomberg Businessweek reported the buyer was Shkreli.

In the 12-minute video, Ghostface calls Shkreli a "fake super villain," and attacks him for threatening to erase the sole copy of Once Upon a Time in Shaolin and flaunting his money recklessly.

He challenged Shkreli to reverse his decision to hike up the price of the drug Daraprim saying: "Give us back that medicine".

Shkreli is accused of using one of his biotechnology companies as a piggy bank to pay off investors who lost money in hedge funds he ran; he has pleaded not guilty. He became infamous last year for raising the price of a rare drug by more than 5,000 percent and provoked further outrage on social media with stunts like spending millions on the album, which music fans are desperate to hear, only to tell Bloomberg Businessweek that he had no immediate plans to listen to it.

Last week Shkreli declined to answer questions in a drug- prices hearing of the U.S. House Committee on Oversight and Government Reform, invoking his Fifth Amendment right not to incriminate himself. Afterward he posted a tweet calling the committee members "imbeciles."
